A practical nurse (PN) is preparing to obtain a capillary blood glucose reading for a client with type 2 diabetes mellitus. To ensure an accurate result and reduce the risk of infection, in what order should the PN perform the following actions? (Arrange the steps in the correct sequence.)
- 1Verify the client's identity using two identifiers and explain the procedure.
- 2Cleanse the lateral aspect of the chosen finger with an alcohol swab.
- 3Allow the cleansed area to dry completely in the air.
- 4Puncture the skin with the lancet and wipe away the first drop of blood using sterile gauze.
- 5Apply the second drop of blood lightly to the test strip and await the reading.
Answer
The correct sequence is to identify the client, cleanse the finger, let it air dry, puncture the skin and wipe the first drop, then test the second drop.
Performing the steps in this specific order guarantees both client safety and the exact accuracy of the diagnostic lab value. Identifying the client is always the priority. Cleansing the site removes surface bacteria and residual sugars. Allowing the alcohol to naturally air dry ensures it does not alter the glucose result or cause a burning sensation upon puncture. Wiping away the first drop of blood is crucial because it contains serous tissue fluid that dilutes the sample. The second drop provides an accurate capillary specimen, which is vital for safe medication administration.
